The links provided don't even address the ability to run higher compression on pump gas without detonation - by using longer rods. All they were talking about is where the hp gain is - low vs high rpm - and torque vs hp - I already know that, or I wouldn't have engineered the bolck to run 6" rods. I built a torque monster of an engine. My powerband is very flat. I am looking for substantial claims of other than 36 total degrees of timing can be run on a 6" rod motor with results. Is this fact or fiction. I have a variable timing module installed - and my Unilite is out getting set up with 28 degrees of total timing on the distributor, all in at 3K.

Helpful suggestions would be good at this point, not a history lesson on rod length.
